Mesin Xubuntu 16.04 yang sepenuhnya ditambal dengan pengguna yang baru dibuat tidak akan membiarkan saya membuka kunci setelah menggunakan light-locker untuk mengunci layar saya (terlepas dari apakah kunci diaktifkan secara manual atau melalui batas waktu). The layar tetap hitam (tapi bertenaga) pada entri password yang benar
Membunuh light-locker dari tty1 akan mengungkapkan desktop itu (dan akibatnya mencegah penguncian lebih lanjut).
Langkah-langkah dicoba:
- diaktifkan / dinonaktifkan kunci dalam pengaturan pengunci cahaya & dalam pengaturan daya (tidak ada perubahan)
- digunakan xscreensaver bukan light-locker (berfungsi)
- diuji jika masalah terkait dengan penangguhan atau penutupan tutup (tidak)
- Namun, setelah menangguhkan layar hitam mengungkapkan
This session is locked: You will be redirected to the unlock dialog automatically in a few seconds
pesan - tanpa redirection
- Namun, setelah menangguhkan layar hitam mengungkapkan
- dibersihkan + instal ulang lightdm, light-locker dan xubuntu-default-settings
- menggunakan
loginctl unlock-session
tidak berpengaruh systemctl status lightdm
hanya mengungkapkan (tidak berbahaya, diharapkan) pesan tentang modul pam kwallet yang hilang- memeriksa log dpkg untuk peningkatan antara "berhasil" dan "tidak berfungsi lagi" (tidak mencurigakan) dan mem-boot kernel sebelumnya (masalah tetap ada)
- Perilaku yang dibandingkan antara pengunci cahaya yang diprakarsai sesi dan yang dimulai secara manual (tidak ada perbedaan)
- menambahkan pengguna ke grup
nopasswdlogin
grup (layar hitam kemudian muncul tepat setelah penguncian, tidak hanya setelah memasukkan kata sandi)
Langkah-langkah tambahan apa yang terbukti bermanfaat dalam mencari cara untuk memperbaikinya?
